China stole the F35 stealth but did not make a compromised fighter
At least twice since 2007 Chinese hackers have stolen data on the F-35 from the developers poorly-guarded computer servers.
China's J-31 jet lacks many of the features that were included in the F-35 that were made for the US Marines obsession with jumpjets. War is Boring also explains why the history of the Harrier and why it was also terrible.
Compromised fighters are not built for maximum speed, acceleration and maneuverability
The J-31 does not have a lift fan or even a space for a lift fan. This allowed Chinese engineers to optimize the new plane for speed, acceleration, maneuverability and flying range and to add good pilot visibility and a second rearward engine instead of having to build the plane around a pretty much useless vertical-takeoff capability that slows it down, limits it to one motor and blocks the pilots view.
The F35 fighter is the aerodynamic equivalent of a lobbed brick, totally outclassed by the latest Russian- and Chinese-made jets.
